Is this a question about the children in the movie? If so, I'm afraid I don't recognize any of the names, but that wouldn't be surprising: very few of the children at School of American ballet who are from NYC and start when they are very young become professional dancers, with Judith Fugate and Peter Boal being notable exceptions. It's mostly the kids who show up as teenagers for pre-professional training that track to companies.
Hope this isn't regarded as :offtopic: but we were watching the PNB Nutcracker movie over the holidays and got to wondering if any of the young dancers in it made professional careers of it. Any PNBophiles know the answer to this?
If you mean the dancers in adult roles, the dancers who retired from PNB are Kevin Kaiser (Moor), Angela Stirling (Observer), who is now a company photographer for PNB, Wade Walthall (Prince), Artistic Director of Evergreen City Ballet, Benjamin Houk (Adult at Party), who was Patricia Barker's long-time partner, led Nashville Ballet and Fort Worth/Dallas (1996-2001) and was a finalist in the search for Russell/Stowell's replacement, and Julie Tobiason (Snowflake/Flower) became a Principal Dancer and retired a few years ago.
Gerard Ebitz (Adult at Party) danced with NYCB and is on the faculty roster for New World School of the Arts. Erica Fischbach danced with ABT after an early career at PNB, but she's no longer listed on the Company's website, although a Google search will lead to a bio that was linked from their site.
To get back on topic, on stage the character of Drosselmeyer isn't quite as creepy as it is in the movie, at least in the first act. He's mean, and keeps picking on Clara and inciting Fritz and his friends to riot, but he's not someone who would require a visit from Social Services.
